DSD (Direct Stream Digital) is one bit audio format for high resolution music. The format based on sigma delta modulation. Read details about DSD >
Music in DSD format may be stored into DSF and DFF files (.dsf and .dff file extensions respectively). Both DFF and DSF are DSD files.
I.e. DSD files is common term, that include both DFF and DSF audio files.
DSD versus DSF versus DFF files
However besides these kind of files, SACD ISO (.iso extension, 1-bit audio ISO) is DSD file too. SACD ISO contains text metadata, that may be extracted during SACD ISO to DSD conversion.
DSF and DFF files are able to contains binary identical audio content.
In .DFF audio content may be losslessly compressed. But it do not impact to sound quality.
Sound quality for both file formats is defined by:

Sometimes one bit DSD considered as more qualitative alternative for multi bit PCM. However it is not simple matter, that defined by implementation. Read more:

All DSD files (DSF, DFF, ISO) may be converted each to other without loses, when conversion don't alter sample rate.
DSD conversion
DSD resampling and other processing (even elementary gain changing) lose quality, comparable with PCM resampling. However it is not big matter for pro-audio processing.

DSD playback may be implemented two ways:
In general, second option is preferable. But real result depend on hardware and software implementation.

Read below about DSF versus DFF playback, compression, editing issues ↓
Playback sound quality is the same for both DFF and DSF.
DSF and DFF on DSD file player
DFF file don't support music metadata (song name, album, performer, artwork) standard way. However, the metadata may be stored as ID3 format into DFF file's chunk (internal data block). For access to the metadata, DFF file player must be able to recognize ID3-chunks.
DSF specification support the metadata. However may be issues with artwork size and/or resolution for DSF audio player.
To playback multichannel music at DSD player, the music is downmixed into stereo on fly. Sound quality of downmixing is implementation matter. To save hard disk space, you can pre-downmix it.

Current DSF specification note raw uncompressed packing only [1].
DFF may be stored as uncompressed as compressed by DST (Direct Stream Transfer) method [2].
From sound quality point of view, for editing DSD files, file format is not matter.
